STUDY OF SOME YIELD COMPONENTS IN DIFFERENT CULTIVARS OF STRAWBERRY PUBLISHEDNATALIA CARP*, CIULCA S
The yield ability in strawberries is a very complex trait that relies on the influence and contribution of several components. Those components must be combined so as to ensure higher levels of yield and a high amount of marketable fruits. The studied biological material was represented by eight varieties with different ecological and genetic origin, which were analyzed in terms of: number of flowers and fruits number per plant, the percentage of ripening fruit, average fruit weight and yield per plant. The most pronounced differences between genotypes were recorded for fruit weight and number of flowers/plant, while in terms of the percentage of fruit ripening the studied cultivars showed similar and statistically undifferentiated values. Taking into account the inter-populations variability for the studied traits, depending on the way they are combined, can be selected cultivars with contrasting traits, in order to use them as genitors. Onda variety has the highest values of plant yield, number of flowers and number of fruits, associated with an average weight of the fruit. Depending on the yield components in different studied cultivars, in order to obtain an efficient yield, technological measures must be taken to foster the development of the traits with higher contributions to the achievement of plant yield.
